The check engine light is on the DIC. The SES light is over by the Security light. The SES light stays on while the car is running. The CE light only comes on when you start the car, then goes off with all other system monitor lights on the DIC.
Maybe a picture is in order....
Rotating the TPS all the way will give you a code for high or low TPS signal.

Is the TPS supposed to be dead center? That how I had it before. :?
I'll test it again when I get home tonight.

TPS should be hooked behind the pin, so the arm moves when the throttle is advanced.
The curved face of the arm should be in contact with the throttle shaft pin. Ignore code 58. It'* a known bug in the 92 PCM.

Update....
I couldn't get the Code 22 to go away. So, I checked the voltage at the harness. 4.98 volts. Perfect.
So, I then tried to test the TPS according to the procedure in the Chiltons. It seemed to not pass the test. So, I bought a new TPS. Installed it. Took the battery cable off for 20 minutes. Before I even started it, I pulled codes. Had the code 22 again. Test drove it. The light was coming on/going off intermittenly. Seemed to go off when I pressed the gas.
Repulled codes. Still a 22. If there was a fault in the wiring, I would expect a 21 or 22. Not just a 22. :? Anyone, anyone?

The book would probably suggest checking the connector and pins, looking over the wiring etc.
Also having recently thought I was the victim of an intermittant ground issue, I would suggest cleaning the grounds. (It'* actually easy, once you get to it).

The ground you're talking about....the one under the driver'* seat?

In your case, yes..I would clean those grounds well. Actually along the drivers inner door sill. Knowing that the car had water leaks, that would be the first place to check. Then at the battery, under the coil pack, front of the motor where the battery cable is hooked up, then at the back of the motor by the oil pressure sender. (this last one is easiest to get to through the passenger wheel well.

Does your voltage vary smoothly from .2-.7 volts at the bottom to about 4 volts at the top?
What effect does it have if you wiggle and shake the harness while checking voltage?
Inspect your pins on the harness. I'd rule out a pin problem on the new sensor.
Code 22 sets if the ignition is on and the TPS voltage is less than .2 volts for 4 seconds or more at any time.
Code 21 sets if TPS voltage is higher than 4.8 volts at any time.
